DESCRIPTION:
A weakness and some vulnerabilities have been reported in Ipswitch
IMail Server, which can be exploited by malicious people to cause a
DoS (Denial of Service).

1) Two boundary errors within SmtpDLL.dll can be exploited to crash
the Queue Manager service (queuemgr.exe) by e.g. sending an e-mail
with a specially crafted sender ("FROM:" field).

Successful exploitation may require that the "Copy All Mail To:" and
the archiving via SMTP options are enabled.

2) A boundary error within IMailSrv.exe when processing certain spool
files can be exploited to cause a stack-based buffer overflow by
sending specially crafted emails containing e.g. multiple "Reply-To:"
or "Resent-From:" headers to the SMTP service. This can be used to
e.g. spawn multiple Windows crash dialogs or fill up the disk space
with spool files.

NOTE: Execution of arbitrary code has not been proven, but cannot be
completely ruled out.

SOLUTION:
Apply IMail v11.02 Patch 2.
